In menuconfig, when you open the help on an item, there is a line |
11 |
"Depends on". If the requirement is not met, the option is not visible |
12 |
but can be found by searching (press /). |
13 |
|
14 |
There might also be a line "Selects" which contains automatically |
15 |
activated dependencies and "Selected by" which contains the reverse |
16 |
dependencies. |

Don't think so. If there is a regression, it should get fixed in the |
22 |
main line kernel. |

What kind of workload do we talk about? Properly "niced" and "ioniced" |
29 |
compile jobs? Is the freeze temporary? |

Odd. Maybe GPU related? Again, does the system recover? |

Doesn't surprise me. P4 and Atom are both horrible micro architectures. |
42 |
But Atom is also horribly stripped down and has a lower clock frequency. |
